A digestive system evaluation is your clear starting point for understanding gut health. It typically involves a combination of tests that look at how your gut microbiome is composed, how it’s functioning, and how well your gut is absorbing and processing what you eat. Expect stool-based analyses to gauge microbiome composition and function, sometimes paired with breath tests to check for issues like SIBO or carbohydrate malabsorption. Your clinician or the testing provider will guide you on preparation, such as timing, fasting requirements, and avoiding certain medications, to ensure the most accurate results. InnerBuddies brings a unique, white-label solution to this space. As a provider of a modular Gut Health Operating System, InnerBuddies powers consumer- and partner-facing gut testing products with a suite of features that translate complex data into usable guidance. The Gut Microbiome Health Index scores your gut health on a 0–100 scale using an exclusive collaboration with EAFIT University in Colombia. You’ll also see Bacteria Abundances and Bacteria Functions, each benchmarked against a healthy cohort to show where you stand. The platform also offers Target Group Analysis for topics like Healthy Aging, Endurance Sport, Power Sport, and Skin & Hair Health, plus Personalized Nutrition and Probiotics/Prebiotics advice tailored to your unique microbiome. Learn more about how this works on the InnerBuddies microbiome test page: InnerBuddies microbiome test. If you’re preparing for a digestive system evaluation, practical prep tips can make a big difference. Follow the test provider’s instructions, which may include avoiding antibiotics for a short window beforehand, staying hydrated, and adhering to any fasting or dietary requirements for specific tests. For stool collection, use the provided kit precisely as directed and ship it within the recommended window. If you’re curious about ongoing support beyond a single evaluation, InnerBuddies also offers direct consumer access to its capabilities, including a subscription option for continued gut health guidance: InnerBuddies Gut Health Membership. For companies interested in powering their own gut testing products, the B2B pathway is available here: InnerBuddies B2B partner page. Understanding the results from a digestive system evaluation becomes practical when you know what to look for and what to do next. The Gut Microbiome Health Index gives a quick read on overall gut health, while the Bacteria Abundances and Bacteria Functions views highlight which beneficial or problematic microbes and activities are influencing your score. With Target Group Analysis, you can see how your results align with goals such as improved athletic performance or healthier aging, and personalized nutrition and probiotic/prebiotic recommendations translate results into real-world actions. After reviewing your results with a clinician, you can plan targeted dietary tweaks, introduce specific probiotic strains if appropriate, and consider a follow-up evaluation to track progress. If you’d like ongoing, structured support, the InnerBuddies subscription can help you stay on course and continue refining your plan.
